Antenna Description


Centimeter-Level Precise Point Positioning and Real-Time Kinematic Advanced Technology

This high precision, high gain stacked patch thru-hole mount antenna (2JCP2582101Gc) is designed for simple integration into demanding GNSS antenna designs that operate within GPS, GLONASS, QZSS, and Galileo standards. By combining Precise Point Positioning (PPP) of L1 and L2 with Real-Time Kinematic (RTK) satellite navigation, this antenna is the first choice for land and hydrographic survey applications. This is possible because it is designed with advanced real-time error corrections while simultaneously maintaining centimeter-level accuracy data when passing through solid objects or high coverage landscapes.

Suggested applications include:

- Land Survey Measuring Instruments
- Hydrographic Survey Instruments
- Unmanned Aerial Vehicle Navigation and Drones
- Autonomous Vehicles
- Civil Aviation boosting the receiver signal

Compatibility Standards


-GPS(L1C/A), QZSS(L1C/A), Galileo(E1B/C)




Installation and Durability

The stacked patch design has a small form factor measuring 25 x 25 x 8 mm allowing for easy off-the-shelf internal integration via thru-hole mount and additional high-quality 5000NS double-sided adhesive. Both patches are constructed from a durable ceramic material, offering durability in temperatures ranging between -40C to +85C. This is a passive single feed antenna.  For applications where the cable runs for more than 100 feet, we recommend adding in-inline amplifiers to account for transmission line loss. Our highly trained experts are available to assist our customers with tuning and integration support for optimal antenna performance.  2J Antennas supports the health of our environment and manufactures all our products without hazardous materials making us fully REACH and RoHS compliant.
